For a while now, /bin should be a link to /usr/bin. is /usr/bin in the
PATH?
That's the most likely issue here. The OP keeps referring to an F20
box and IIRC that predates the /bin<-->/usr/bin changeover.
To answer the question, bash has an initial PATH compiled into it.
What that PATH contains depends on how bash was built and how bash
was launched (they inherit the environment of the launching process--
interactive or not). The vast majority of systems bugger that default
path by use of the /etc/bashrc script and possibly custom scripts in
/etc/profile.d.
Interactive (login) shells are typically launched by the login process
and inherit the login process' PATH (see "man login" for details). The
additional stuff (/etc/bashrc, /etc/profile, etc.) are also invoked.
A chrooted shell gets its environment from the chroot process and would
run any normal startup scripts, but they'd be from the chrooted /etc,
not necessarily the root system's /etc.
